The mill can accept up to approximately 4mL of material, although optimum grinding efficiency is usually achieved with a 2mL sample. The advantage of our mill is that the analyst can examine the sample after a 10-minute grind and if it is not fine enough, put it back on and grind for an additional 5-10 minutes depending on size to be achieved.

The early mills had horizontal paddle wheels, an arrangement which later became known as the "Norse wheel", as many were found in Scandinavia.The paddle wheel was attached to a shaft which was, in turn, attached to the centre of the millstone called the "runner stone". The turning force produced by the water on the paddles was transferred directly to the runner stone, …

Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by …
